SOAP-MAKIXNG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 457,914, dated August18, 1891.

Application filed January 28, 1890- Serial No. 338,400. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM A. GRANT, a citizen of the United States,residing; at Houston, county of Harris, State of Texas, have invented anew and useful Improvement in Soap-Making Apparatus, of which thefollow-- ing is a specification.

Myinvention relates to apparatus for maklng soap; and it consists inimproved mechanlsm, as herein described, whereby the same frames areemployed in mixing the ingredients and in cooling the prepared mass,thus obviating the necessity of the removal of the mixed mass from themixing-frame to a cooling-frame.

The mechanism embodied in my invention is illustrated in theaccompanying drawings, in which Figure 1 is a side elevation of theapparatus embodying the invention. Fig. 2 is an elevation of theapparatus at right angles to that shown in Fig. 1. Fig. 3 is a planview. Fig. at is a horizontal section on line y y, Fig. 1. Fig. 5 is ahorizontal section on line it a: of Fig. 2.

Similar letters refer to similar parts throughout the several views.

Arepresents a metal column or standard having a base B. To the top ofthe column is secured a plate or flange C, and on top of the latter isbolted a boss D, having the radial arms E E E. The outer ends of each ofthe arms E is formed with a boss or box, which serves as a bearing forone of the mixershafts G. The mixer-shafts G, which in the apparatusshown are three in number, are each provided at their lower ends withthe transverse mixer-blades a for agitating the ingredients in themixing-box A. Connected with the boss D, on the opposite side from thearms E, are the horizontally-extending curved arms H H, the outer endsof which support the boxes H H. The driving=shaft J has bearings in theboxes H H, and has on one end the bevel gear-wheel R and on the otherend the fast and loose pulleys K and K.

Supporting the arms E E E are the braces M, bolted at their lower endsto the column A.

The curved arms H and the braces L, secured to the boxes H and thecolumn A, aid in supporting the driving-shaft.

On the boss D is bolted a boss or flange N,

. and formed integral therewith is the circular hood or ring 0, thelatter having connected therewith on the top and opposite to the boss Dthe box P, which serves as a bearing for the vertical shaft Q, the lowerend of which is stepped into the bosses or flanges N and D. On the shaftQ is secured the bevel gear-wheel R and the cog-wheel S, the formermeshing with the bevel gear-Wheel R of the shaft J and the latter withthe gear-Wheel T on the center mixer-shaft G. On the side mixershafts Gare the gear-wheels U, each meshing with the gear-wheel T. (SeeFig. 3.)

The lifting-bar V, which is located below the hub of the gear-wheels U TU, is provided at its outer ends with the tongued wings X X, and hasbosses or boxes through which pass the mixer-shafts G. The oil-cups Ware formed in the upper faces of the said boxes.

Z represents wooden supports to which are secured the metal groovedplates Y, in which the tongues of the wings X are adapted to move. v

The mixer-shafts G G G are kept in line while being lifted out of andlowered into the mixing or cooling frames by a bar 0, which is providedwith bosses, through which said shafts G G G pass. To the rear of thebar 0 and at right angles therewith are fastened the horizontal arms d,having at their rear ends bosses adapted to slide on the verticalguide-rods e, the latter having at their upper and lower ends thehorizontal arms f, which are firmly secured to the column A.

To the wings X X of the lifting-bar are secured the eyebolts g, the eyeportions of which extend above the Wheels U U, as shown. A bent iron rodh is fastened at its ends to the eyebolts and has attached at its centeran iron or other rope h, which passes over the pulleys j j, and hasattached to its end an equipoise-weight 7.; to balance the mixer-shaftsand connected parts. A cord or rope Z, with hand-piece m, is secured tothe weight, so that the mixer-shafts may be readily raised or lowered,as desired.

The operation of the apparatus is as follows: A mixing-frame having beenplaced in position, the mixer-shafts are lowered into the same and thedriving shafts operated by means of power communicated from any suitablemotor to the fast pulley K. This commitnit ates rotary motion by thebevel wheels R R to theshaft Q and gear-wheel S, and thus to thegear-wheels T and U U, the latter two being rotated in oppositedirections and at a different rate of speed from the Wheel T. lVhen theingredients have been thoroughly mixed, the mixer-shafts are raised outof the frame 12 by lowering the cord Z, so as to raise the lifting-barV, and thereby the mixershafts G and the gears T U U, the tongued wingsX of the bar V working in the grooves Y and the bosses of the arms (1sliding on the guide-rods 6, thereby preserving a right-line movement ofthe said parts.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

1. In a soap-manufacturing apparatus, the combination of a mixing-frame,a series of mixer-shafts with transverse blades, a stand ard with theflange O at the top thereof, the boss D on the said flange, the radialarms E E E on the said boss and having bosses at their outer endsserving as bearings for the mixenshafts, the curved arms H, with boxesat their outer ends, a rotatable shaft journaled in said boxes andhaving thereon the bevel gear-wheel R and the fast and loose pulleys Kand K, respectively, the shaft Q, with gear-wheel R and cog-wheel S, thegearwheel T on the center mixer-shaft gearing with the wheel S, andthegear-wheels U on the side mixer-shafts and gearing with the said wheel'1, substantially as described.

2. The combination of a mixing-Hattie. a standard with a flange on itstop, a boss l), secured on top of said flange and having radial armswith bosses in their outer ends, rising and falling mixer-shafts havinghearings in said bosses and provided with transverse blades, horizontalcurved arms with boxes at their outer ends, the rotatable shaft J,journaled in said boxes and having the bevel gearwheel R thereon, theflange N, secured to said boss T), the ring 0, with the box 1? oppositethe boss D, the vertical shaft Q, with the gearwheel R and the cog-wheelS, and cog-wheels on said mixer shafts, substantially as described.

3. The combination of a mixing-frame, the mixer-shafts with horizontalgear-wheels thereon, a lifting-bar below said gear-wheels and adapted toraise the same with the mixer-shafts, tongued wings on said bar, asupport having grooved plates secured thereto, eyebolts secured to saidwings, a rod bent in center and secured at its ends to said eyebolts, arope secured to said rod, pulleys over which said rope passes, abalance-weight on one end of said rope, a standard and a verticalguide-rod secured thereto, and a horizontal bar with arms movable onsaid guide-rod, substantially as described.
